The aim of this paper was to compare the different shapes of theconformal cooling channels (CCC) with constant surface area and CCC with constantvolume in injection molding using Mold-flow Insight 2016 software. Also the CCC resultswere compared with conventional cooling channels. Four different shapes of the CCC suchas circular, elliptical, rectangular and semi-circular were proposed. The locations of thecooling channels were also kept constant. The results in terms of cooling time, cycle timereduction and improvement in quality of the product shows that no significant effect ofCCC’s shapes when surface area of CCC kept constant. On the other hand, the rectangularCCC shows better result as compared to other shapes of CCC when volume of CCC werekept constant.展开更多
